Low-Contamination Powder Processing
MeltPrep develops advanced laboratory technologies for rapid, lossless preparation of thermoplastic samples, enabling precise material characterization and formulation development.
Vacuum Compression Moulding (VCM) technology transforms powders into homogeneous, bubble-free specimens within minutes while preserving original material properties.
VCM (Vacuum Compression Moulding) allows the mg-to-g scale screening of new formulations for hot-melt extrusion (HME). VCM is a process that transforms thermoplastic materials into homogeneous specimens without altering the source materials’ characteristics due to degradation.
Pellets or powder etc.
Perfect samples
Step 1 : Vacuum compaction
The desired amount of materials is filled into the VCM Tool. Vacuum is applied, compacting the powder as well as preventing bubbles.
Step 2 : Melting
Rapid melting is achieved by heating the VCM Tool on a preheated hot plate. Particles fuse to create a homogenous melt.
Step 3 : Cooling
Rapid cooling of the VCM Tool is obtained by convection and conduction on a separate cooling unit solidifying the sample.
The VCM Process holds the balance between input and output material. It’s the first lossless approach to melt samples into a defined shape without air inclusions. With 1 gram of powder, you will obtain a cylindrical sample of 1 gram with a defined shape.
For certain applications, even 1 g may represent an excessively large material quantity; therefore, the VCM technology has been miniaturized to diameters as small as 2 mm. Rods with a 2 mm diameter can be produced with heights ranging from 0.1 mm to 10 mm, enabling high-throughput screening and accurate material characterization starting from the low milligram range.
